The all-new 2026 Kia K4 enters the compact sedan segment with a clear strategy: redefine value by offering features, space, and technology that competitors reserve for higher price tiers. With five distinct trim levels—LX, EX, EX+, GT-Line Turbo, and GT-Line Turbo Limited—the K4 provides a logical walk-up from well-equipped base model to sporty, technology-rich flagship. For Owen Sound buyers evaluating which configuration delivers the right balance of equipment and budget, understanding the specific differences between these trims proves essential.
All K4 models share segment-leading interior dimensions that set them apart from traditional compact sedans. At 4,710 mm length, 1,850 mm width, and 2,720 mm wheelbase, the K4 measures larger than the Honda Civic, Mazda3, and Volkswagen Jetta. This size advantage translates directly into 964 mm of rear legroom—genuinely comfortable space for adult passengers rather than the cramped quarters typical of this class. The 413 L trunk provides cargo capacity that rivals midsize sedans, accommodating luggage, sports equipment, or weekly grocery runs with room to spare.
LX: The Foundation
The base LX trim establishes a solid starting point with the 2.0-litre MPI 4-cylinder engine producing 147 horsepower and 132 lb-ft of torque, paired with an Intelligent Variable Transmission (IVT). Combined fuel economy of 7.0 L/100 km balances efficiency with performance for daily commuting and highway travel between Owen Sound and larger centres.
Technology equipment includes a 12.3-inch multimedia interface with wireless Apple CarPlay and Android Auto, eliminating cable connections for smartphone integration. The 4.2-inch Supervision LCD/TFT instrument cluster provides essential driving information in a clear, readable format. Four-speaker audio, HD Radio, SiriusXM satellite radio (3-month trial), and Bluetooth connectivity handle entertainment and hands-free calling.
Smart Key with push-button start includes remote car starter capability, allowing drivers to precondition the cabin during Grey County's winter months before stepping outside. Smart Cruise Control with idle Stop & Go technology maintains set speeds and distances from vehicles ahead, reducing driver workload during highway cruising.
Safety systems include Highway Driving Assist (HDA), Forward Collision-Avoidance Assist, Lane Following Assist, Lane Keeping Assist, Blind-Spot Collision-Avoidance Assist, Rear Cross-Traffic Collision-Avoidance Assist, and a rearview camera with dynamic guidelines. This comprehensive suite monitors surroundings and intervenes when potential collisions are detected.
The LX rides on 16-inch steel wheels with covers, fitted with 205/55R16 tires. LED multi-reflection headlights, LED DRL and positioning lights, and LED high-mounted stop lamp provide modern lighting. Inside, cloth seats, heated front seats, height-adjustable front seats, 60:40 split-folding rear seats, air conditioning, power windows with express up/down driver window, and tilt-telescopic steering wheel create a comfortable environment.
Best for: Budget-conscious buyers seeking the complete K4 experience—segment-leading space, essential technology, comprehensive safety systems—at the most accessible price point.
EX: Enhanced Connectivity and Comfort
The EX trim upgrades key areas while maintaining the 2.0-litre engine and IVT transmission. Exterior improvements include 17-inch alloy wheels (up from 16-inch steel) with 225/45R17 tires, improving visual presence and ride quality.
Technology advances with six-speaker audio (up from four) and expanded USB charging capability. Kia Connect (3-year complimentary subscription) provides smartphone-based support services including remote start, vehicle status monitoring, and maintenance alerts. Wireless phone charger keeps compatible devices powered without cables.
Interior refinements include rear climate ventilation, illuminated and sliding sun visors, artificial leather-wrapped shift knob, and satin chrome interior door handles. Black high-glossy interior accents modernize the cabin aesthetic. Power windows expand to include obstacle-detecting driver window, protecting against accidental closure.
Drive Mode Select allows drivers to adjust throttle response and transmission behavior across multiple settings, customizing the K4's character for different situations. The electronic parking brake receives autohold functionality, maintaining brake pressure at stoplights without requiring foot pressure.
Best for: Buyers seeking enhanced comfort and connectivity features while maintaining efficiency-focused powertrain and accessible pricing.
EX+: Technology and Refinement
The EX+ builds on the EX foundation with meaningful technology and interior upgrades. The acoustic laminated windshield reduces road noise, creating a quieter cabin environment for highway travel. The full-width power sunroof adds natural light and ventilation.
Synthetic leather seats replace cloth upholstery, elevating interior aesthetics. Front windows gain express up/down functionality with obstacle detection, matching the driver's window capability. Dual-zone automatic climate control with automatic defog system replaces single-zone air conditioning, allowing independent temperature settings for driver and passenger.
The 4.2-inch instrument cluster remains unchanged, but interior mood lights add ambient lighting that creates a more refined atmosphere during evening driving.
Best for: Families prioritizing comfort and convenience features—sunroof, synthetic leather, dual-zone climate—while staying with the efficient base powertrain.
GT-Line Turbo: Performance and Premium Technology

The GT-Line Turbo marks a substantial departure from the base trims through powertrain, suspension, technology, and equipment upgrades. The 1.6-litre turbocharged GDI 4-cylinder engine produces 190 horsepower and 195 lb-ft of torque—a 29% power increase over the base engine—paired with an 8-speed automatic transmission. Combined fuel economy of 8.0 L/100 km represents a modest 1.0 L/100 km penalty for significantly enhanced performance.
The multi-link rear suspension replaces the coupled torsion beam axle, improving wheel control and cornering stability. Larger disc brakes—12.0-inch vented fronts (up from 11.0 inches) and 11.2-inch solid rears (up from 10.0 inches)—provide stronger stopping power. 18-inch alloy wheels with 235/40R18 tires enhance grip and visual presence.
Technology receives a comprehensive upgrade. The 12.3-inch TFT Supervision cluster with 5-inch designated HVAC display replaces the 4.2-inch unit, creating a nearly 30-inch panoramic display configuration when combined with the 12.3-inch touchscreen. Integrated navigation eliminates the need for smartphone apps during unfamiliar routes. Voice recognition enables hands-free control of key functions.
Small cube projection LED headlamps with integrated LED fog lamps deliver superior nighttime visibility. Blind-spot view monitor displays the corresponding blind spot area in the instrument cluster when the turn signal is activated. Surround View Monitor (SVM) provides a 360-degree perspective of the vehicle's surroundings, simplifying parking maneuvers.
Interior equipment includes GT-Line style synthetic leather seats, power-adjustable driver's seat with lumbar support, heated rear seats, sport steering wheel with paddle shifters, rear centre armrest with cupholders, and interior mood lighting. GT-Line design accents differentiate the exterior appearance.
Best for: Performance-oriented buyers seeking turbocharged acceleration, enhanced handling, and premium technology in a compact sedan package.
GT-Line Turbo Limited: The Complete Package
The range-topping GT-Line Turbo Limited builds on the GT-Line Turbo with additional refinements and convenience features. Power driver seat gains memory system functionality, automatically recalling saved positions. Digital Key 2.0 transforms compatible smartphones into secure keys, enabling remote door lock/unlock and vehicle starting without carrying a physical key fob.
Audio upgrades to the Harman Kardon premium sound system, delivering enhanced clarity and depth across strategically positioned speakers. The artificial leather-wrapped sport steering wheel adds heating functionality for cold-weather comfort.
18-inch black alloy wheels (replacing the standard 18-inch alloys on GT-Line Turbo) provide additional visual differentiation and a more aggressive appearance.
Best for: Buyers seeking every available feature and the most refined K4 experience with comprehensive technology, premium audio, and flagship equipment.
Shared Strengths Across All Trims
Regardless of trim selection, every 2026 K4 delivers the same segment-leading dimensions: 4,710 mm length, 964 mm rear legroom, and 413 L trunk capacity.

All trims include front-wheel drive, electronic power steering, electronic parking brake, PTC heater, 60:40 split-folding rear seats, rear floor heating duct, central door lock, LED interior lighting, and comprehensive safety systems. The 47 L fuel tank provides 600+ kilometres of range (base engine) or 550+ kilometres (turbo engine), eliminating frequent fuel stops during regional travel.
Kia's 5-year/100,000 km comprehensive warranty, 5-year/100,000 km powertrain warranty, and 5-year unlimited km roadside assistance provide peace of mind regardless of which trim is selected.
